Copper and Chlorine
Cu ClCl
Copper + chlorine=Copper (II) chloride, CuCl2
This is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate. Copper (II) chloride is used to make fungicides. It is also used to make organic compounds. Copper (ll) chloride is a compound because it has two other different elements combined together, which are Zinc and Oxygen.

2Fe + O2 → 2FeO
Iron(II) oxide, also known as ferrous oxide or informally as iron monoxide, is one of the iron oxides. It is a black-colored powder with the chemical formula FeO. It consists of the chemical element iron in the oxidation state of 2 bonded to oxygen

AMMONIA!
1 nitrogen atom and 3 hydrogen atoms makes Ammonia. (NH3) Ammonia is a colourless gas with a sharp, penetrating odour. Its boiling point is −33.35 °C (−28.03 °F), and its freezing point is −77.7 °C . It can be handled as a liquid in thermally insulated containers in the laboratory. (The heat of vaporization of a substance is the number of kilojoules needed to vaporize one mole of the substance with no change in temperature.)
